Description

If you’ve noticed oil spots under your tractor after hooking up to PTO implements, chances are your pulley box seal has given up the ghost. That little seal might seem minor, but when it fails, you’ll get hydraulic fluid leaking from the PTO area, contamination getting into places it shouldn’t be, and eventual damage to expensive transmission components. This replacement seal stops the mess and keeps your PTO system running clean and efficient.

Key Features

Direct replacement seal fits perfectly in the PTO pulley box housing without modifications
Quality rubber construction resists hydraulic fluid breakdown and temperature extremes
Precision-molded dimensions ensure proper compression and reliable sealing
Designed to handle the constant pressure and movement of PTO operation

Built for Real Farm Work

This seal works across multiple generations of legendary Massey Ferguson tractors, from the compact 35 series utility machines up through the bigger 550s. Whether you’re running a brush hog, operating a PTO-driven baler, or powering hydraulic implements, these tractors see hard work every day. The PTO pulley box keeps everything turning smoothly while this seal keeps the oil where it belongs.

Made to Last

Farm equipment seals take a beating from temperature swings, constant vibration, and hydraulic pressure cycles. This seal uses materials specifically chosen to handle those conditions without hardening, cracking, or losing its sealing ability over time.

Installation Notes

Clean the pulley box housing thoroughly before installing the new seal, and check for any scoring or damage that might cause premature failure. A light coating of hydraulic fluid on the seal lip makes installation easier and helps prevent damage during assembly.
